Cause

Angola's war of independence originated in Angolan resistance to Portuguese colonial policies, particularly the forced cultivation of cotton. As opposition to colonial authority spread, three major nationalist movements—the MPLA, UNITA, and FNLA—emerged and competed for influence, leading to a sustained guerrilla campaign against Portuguese military and security forces across Angola's vast countryside.

Event

From 1961 to 1974, Angolan nationalist forces waged a guerrilla war against Portugal's colonial administration. The Portuguese army conducted counter-insurgency operations across sparsely populated regions. The conflict ended when a peaceful coup in Lisbon in April 1974 overthrew the Estado Novo dictatorship, after which Portugal declared its intention to grant independence to its African colonies without delay.

Consequence

The Alvor Agreement, signed in January 1975 between Portugal, MPLA, UNITA, and FNLA, formally ended the war and set Angola's independence for November 11, 1975. However, the fragile peace collapsed by May 1975, with civil war resuming among the nationalist factions, including street fighting in the capital Luanda, inaugurating a prolonged Angolan Civil War.
